But wait a second. There are problems.

Problems?

While ​all the brands and manufacturers will show you shiny advertisements and boxes full of lucrative features. But what’s inside the box often comes to be quite different in action. So Ultimately the best way is to take an expert’s help who’d been through these for years. And who knows how to pick the diamond out of all the glittering pieces of glass.

The good news is, we’ve done ​precisely that in this article.

Grab a cup of coffee and keep reading through. We promise you that you’ll find the right pick of th​e best smart thermostat for your home.

What Do We Like Most?

Welcome to our #1 pick of the list of best smart thermostats. The thermostat is ecobee4, which is already quite popular among home users like you and me. It’s basically the upgrade of ecobee3, with some significant updates in ​Sensors, ​Functionality and lots of ​Features.

What we loved most about ecobee4 is its remote sensor. It will let you configure with other systems like HVAC. The actual home thermostat is tucked away from other main parts of the sensors. So, such an attempt to put all these tiny sensors is a big deal to comfort.

The Good

​​Smooth and comfortable temperature adjustment.

​Supports both Android and iOS commands.

​Compatible with Amazon Alexa, Apple Homekit, and Google Home.

Built-in Alexa voice intake service.

​Helps to manage cold and hot spots in the home.

Reduces cooling and heating cost up to 23%.

check-circle

​Easy, and fast to install.

The Drawbacks

​Poor execution of implementation with Alexa.

Let’s glide through other ​useful features of ecobee4.

Product Overview

Design:

Ecobee may not be able to provide a better design in ecobee4, comparing Nest Learning or similar popular thermostats. But apart from the design, it stands out in every other feature. It’s got a perfect combination of smart and touch-sensitive display, fast responsiveness, remote sensor, motion/temperature/proximity detection and many more.

Let's have a quick review of some of its frontline features-

​Features​:

The ecobe4 looks almost like the earlier version ecobee3, but there are some certain differences made it stand out of all smart thermostats in the current market. It has accommodated a speaker and a microphone that can let you hear jokes, temperate change in hoe, weather updates and play music for ​Amazon music service.

Another good news is, ecobee has started to support Google Assistant too. Apart from these few upgrades, the other sensors are identical to ecobee3. The remote sensor, the app, functions, touch interface and everything else are just the same ​as ecobee3.

Sensors:

The remote sensor, which is way better than a remote thermometer, will configure your communication with the HVAC system. Moving forward, one terrific feature of ecobee4 is, it can set the temperature based on the ​central unit and sensor together. I am so surprised that why other manufacturers haven’t stolen this feature yet!

The motion sensor and remote sensor helps the device together to set up the temperature accordingly when someone enters the room. Also, setting up this little magic box is quite ​a straightforward affair. Three different modes- sleep/home/away helps you with more complicated schedule adjustments.

Warranty:

​Ecobee4 comes with three years of official warranty. Which is good enough to secure ​your investment in this smart thermostat for a long time.

If you were happy with ecobee3, you’ll love ecobee4 even more.

Runner Up- Nest Learning Thermostat

What Do We Like Most?

Our second pick is the Nest Learning Thermostat (3rd gen) that is remarkably popular in the market, which is already the closest competitor ​to ecobee4, ecobee3, and others. If you ask us, we’ll bring its ​unique self-learning management into your attention. Thanks to an array of sensors and its advanced learning algorithms, it picks up when someone is moving around, connects the dots if you do it at roughly the same time each day and programs itself in response.

The Good

​Automatically learns what temperature to set itself.

​Integrates with Google Home & Amazon Alexa.

​Powered by a lithium-ion rechargeable battery.

​No C wire is required for installation, making the Nest viable for older setups.

The Drawbacks

​In rare cases, a hardware fault is present which can lead to the battery running out of power.

​The first-time installation is​ a bit hard.

Product Overview

Nest might not have been the first smart thermostat on the market, but its first generation was​ a trendsetter that did a lot of good in convincing people that a smarter home needed an intelligent upgrade to its climate control system. The fact that it looked more like a futuristic gadget than a run-of-the-mill thermostat did much to captivate the imaginations of tech enthusiasts and added to its popularity.

​Versions:

The 3rd generation of Nest has built upon this foundation, and the result is a thermostat that’s more intuitive, has features users themselves requested and, best of all, frees up time you’d waste on programming and monitoring it by actually learning when and how it should be active.

We've already told you about its sensors and the advanced learning technology. It will program itself according to your habits at home.

Warranty:

Nest Learning Thermostat is available in the market with two years limited warranty. You can avail the service by their customer support website (​nest.com/support) or phone call.

The result is a climate-controlled environment you can adjust yourself at any time, but don’t have to. The Nest even indicates which temperature settings save the most energy and its app allows you to review your expenses and take appropriate action on-the-fly.

Our Budget Pick- Ecobee3 Lite

What Do We Like Most?

Here we've got the terribly famous Ecobee3 Lite Thermostat, one of the revolutionary models since 2011 in the industry. It’s the lite version of Ecobee3, with a little compromise in some features and price. So, it’s our budget pick as well.

We love the way Ecobee3 Lite Thermostat reads and teaches itself to adjust home temperatures. In its ​primary mode, the Ecobee3 lite takes readings from all the sensors and averages them out, making sure all parts of the home are equally warm. Adding motion detection into the mix, as well as the ability to not take individual sensors into consideration, tailors the thermostat’s activity to your needs throughout the day without having to put much work into it past the initial setup.

The Good

​Offers a comprehensive solution to HVAC control.

​Takes readings from sensors & calculates optimum settings.

​Sleep and away settings automatically turn the thermostat off/on.

​The more sensors you buy, the more detailed their readings get.

​Ecobee3 lite to more reliably maintain the ideal temperature all day long

​Beautiful, simple appearance that’s ​entirely in line with modern home aesthetics

check-circle

​Comes with one additional external sensor

check-circle

​Doesn’t require batteries.

check-circle

​Can be controlled via touchscreen, voice or app.

check-circle

​Supports a variety of home integration technologies

The Drawbacks

​You only get two sensors with the initial purchase. Requires you to buy more.

​Overlapping away mode causes the heating to re-engage for a time.

Product Overview

Another one of the first major smart thermostats that have emerged since 2011, the Ecobee3 lite is somewhat similar in appearance to the Nest with its black rounded box design and minimalistic touch screen. They differ ​significantly in their approach to smart temperature control though.

​Technology:

The Ecobee3 lite eschews learning about your habits for info gathered through its multi-purpose sensors. These can sense both heat and movement, allowing the ​central thermostat to act on either or both.

You’ll require a C wire to install it, but the process itself doesn’t take long. Once it’s up and running, this advanced version of the Ecobee3 takes control of not just temperature regulation, but ventilation and (de)humidifiers if they’re present too.

Control:

Data on all aspects of your home's microclimate can be viewed at a glance at any time from the touchscreen or requested by voice through Apple HomeKit, Amazon Alexa, and other means.

In short, if you’ve got a large home whose various parts don’t require your thermostat’s equal attention and want to address this problem in a high-tech, comfortable way, the Ecobee3 presents itself as your optimal choice.

Warranty:

​ecobee3 Lite also offers 3 years of warranty. So that you can take this without having much worries.

Budget Runner Up-Honeywell Lyric T5

What Do We Like Most?

From the early days, Honeywell the brand had been able to draw a a reasonable promise of quality is the thermostats that they've released yet. With the same impression, we've elected Honeywell Lyric T5 Review on this list. Moreover, as per as it's seen, we're not wrong at all. This simple and effective thermostat is our budget runner-up due to these features and ​an excellent price.

The difference between another Honeywell model (Lyric round) and this Honeywell Lyric T5 is, it’s a thinner and lighter version of the previous one. So, it will be less expensive as well.

Moving forward, it will send push notifications when the temperature or humidity of your home will change at a significant level.

Like any best smart thermostats, it's an efficient device for balancing the imperfect temperature of any room of the house. Based on the current temperature, it will do the job itself. And like I said, it will send you emergency notifications in emergency cases.

We liked the way Honeywell made this device an easy-to-install one. Even the first-time user can go smoothly while installing it.

Warranty:

​Well, ​it's include two years of warranty. But when you get it installed by a Professional contractor, you'll get ​five years of warranty of the Honeywell Lyric T5.

Best Overall: Sensi Touch Wi-Fi Smart Thermostat [ST75/ST75w]

​What Do We Like Most?

What we loved most about Sensi Smart Thermostat is, it’s a combination of all of the ​ethical virtues that a smart thermostat should have.

​Is more expensive than Emerson’s basic model

Product Overview

Sensi Touch Wi-Fi thermostat is another of an advanced model of the thermostat of the market. It’s hard not to draw parallels between this model and Emerson’s other entry. In short, they share almost all of their positive traits while the Touch has a few of its own advantages and shortcomings brought on by the different screen.

Mobile App:

Most importantly though, you get to take advantage of everything that’s included in the Sensi app. Just make a new account on Sensi’s homepage and download the app to your phone / PC.

Installing the smart thermostat will be a breeze by following along with the tutorials. The scheduler and geofencing make a comeback too, as do the lockout abilities and integration with a slew of automation services.

Difference:

So, what’s different? Apart from the obviously more modern touchscreen that’s a testament to simple and efficient user interface design, not much.

Other ​notable differences include the need to have a common wire handy for installation, control by different users that are privy to the app’s password, no more loss of functionality if the Wi-Fi ever goes out, and support for Apple’s home automation service, HomeKit.

What should you consider before buying a ​thermostat?

​​​

Compatibility of A Smart Thermostat with Alexa/Google/Apple Homekit

One of the ​most impressive features that made smart thermostats a day-to-day gadget for every home, is its compatibility with ​intelligent home assistants like Amazon's Alexa, Google or Apple Homekit. Think about a smart thermostat combined with Amazon’s Alexa / Google. You can set the temperature of a room, change it or set it to any value just with a voice command like these-

Alexa set the bedroom temperature to 55 degrees.

Hey ​Google set the ‘Thermostat’ to 65 degrees.

​Increase the temperature of the living room by 4 degrees.

All you have to do is just saying it. The home assistant and thermostat will take over and do the rest. There are even some manufacturer-specific Alexa commands. Brands like Ecobee, Nest has got their own chart of Alexa commands that made the task even better.

Checking Compatibility:

To ​test whether your thermostat is compatible with smart home assistants or not, you have to check the manufacturer’s guide. If you find something like ‘Works with Alexa/Google Home/Apple HomeKit’, put a smile on your face.

One good news is, most of the devices we've listed here, are compatible with these smart home assistants. For a better view, here are some of the brands that produce thermostats with built-in compatibility-

Ecobee4/ Ecobe3 or Ecobee3 Lite

HVAC System- What and Why?

One of the very few terms that comes to a smart thermostat is the HVAC system of the home. HVAC stands for Heating, Ventilation and Air Conditioning. Although they are different terms in action, in modern households, they've combined into one system.

The reason for HVAC becoming so important is, heating and cooling is the ​primary utility charge taker of any home. Unless you are living in ​an entirely natural climate, HVAC system will take 44% of your entire utility cost every year.

To cut out this cost, you should be very concerned about the consumption, use, and recycling of energy. ​Also, that's where the HVAC system and Smart Thermostats connects to each other.

The discussion of HVAC and Smart thermostats is quite a complex one. ​However, let’s start it straightforwardly-

The question that most thermostat owners should ask is- Is the HVAC system of my home is compatible with the smart thermostat I'm thinking to buy?

Well, to pursue the answer to the question, let's have a glance at ​different voltage system and wiring. Because the compatibility of your home's HVAC system and a smart thermostat will depend on how low voltage the system has. Usually, households have two kinds of voltage systems- the 120v one and the 24V one.

How to Identify A 24v System?

If you have two or more wire in the wiring.

Two of the wires are low gauge compared to the typical ​cable.

​When you have some heating vents on the floor.

If you have a furnace somewhere in the house.

​Any kind of central heat conditioners like a heat pump, boiler or a split system.

​​Two wires are multicolored.

If the thermostat setting affects more than one room.

​​​​On these terms, you have one of more than one sign of the list common to your home, and ​you have a 24v HVAC system in the house, which is ​suitable for smart thermostats.

How to Identify A 120v System?

If there are 2 or 4 wires which are thick is size.

​​The heater of the house operated on a room-by-room basis.

Watch of the rooms has its own thermostat dial.

You have either radiant, resistance or convection heater.

​When the house is a cabin, cottage, ski lodge, apartment or a condo.

If you have any of these signs at the place you’re living in, you need to modify a standard smart thermostat or purchase a modified one.

How to Install A Smart Thermostat Properly

If you've got the right pick of the smart thermostat in hand, now it's time to install it properly. Here is the 3-step guide to set up a smart thermostat-

Step 1: Unbox it And Get Familiar with ItUnbox the thermostat in your hands and check the compatibility of it with the wiring system. If you find a thick set of wires on the box, a smart thermostat is probably not for your home. Otherwise, if you have wires marked ‘Common’, then there is a chance. If you can’t locate the c-wire, consult with your local electrician.

Step 2: Check the CompatibilityCheck the compatibility of the smart thermostat with the voltage system. If they match, then connect the labeled wires to the respective ports. Connect the face plate and finally check the connection and turn on the circuit breaker.

Step 3: Setup and Connect it to the Internet and Wifi.

Now it the thermostat is done with setting up, it's time to connect it to the internet and wifi. If you have a router that’s more than three years old, the router may not support a smart thermostat. So, make sure you can get a new router if necessary.

Great work! Pat your back.
